I'm looking for a oneshot about a girl who looks and seems popular and all the girls keep going to her for love advice. But in reality, she has never experienced love before. Then she meets this guy. I forgot what happened in the middle but at the end, she goes to his highschool and confesses to him.

If you think you know, please tell me.
Thanks!!!

(edit) I also remember the guy has dark hair. And i think it was in a group of oneshots, so not on it's own.
